Well done Andy, a very poetic write up. If only Jon could get the benefit of the words. That's probably the best session you've reported on....... ever!!
(except from my boat of course). 🤣
Who cares how much they are bought for from the Chinese 🤷🏻♂️. The fact is, even after a few years abuse and a new set of rings the blanks are really good..
It's something I attempted a couple of years ago, but never went at it seriously. TBH I don't need to do it as I just point and put on auto. But if not too/tu complicated or expensive I might/mite have a go!
If Jon gets his auto pilot working in conjunction with his plotter, can I do the same with mine?
here is the manual and I have a gpsmap 8410.
